'This invention relates to a joint for wires and wire ropes in which lthe ends to be joined are clamped in a. double muil. Whilst up to the present the clampin was eected with the aidof conical rou ened parts to be clamped which are clamped autof mstically 'in the conically tapered ends of `the double mui when the wires or wire ropes were put under ltension,vthis invention con- 10 sistsv in that without the use of separate clamping elements the one of the wire end's orelements of the joint ,is forcibly ressed into the roughened or channeled sur ace of the other wire end or element of the joint.

. This'invention has for its-object to effect of broken wires rapidly a lasting joinin ocking frames in a 0r wire ropes in railway simple andcheap manner. The invention .further presents the -advantxge. that cross connections may be easily joine to continuous wires;

-The'specisl arrangement of the -chasers is also new. 1

The invention may be executed in diifer- `ent manners, several embodiments of the same being shown by weyy of example Ionv the accompanying drawing, wherein: Fig. 1 shows 1n lo itudinal section the joint for two wires. 5 Fig. 2- is e. longitudinal section online I-I of Fi Fig. f3 slows in longitudinal section the joint of a wire rope and of a wire.

l' The joint 4in its most -simple construction,

1n Figs." 1 and 2, consists if a` mui u: which has :smooth boring. The ends of the two wires B',. b" are threaded but -onlyfer auch -a distance that thsthreededparts of..

the two wire ends together are shorter than the mul a. After the wire ends to be joined have been inserted into the mui,'the muif is compressed with thel except-ion of its outer ends, so that the thread of the wire ends is pressed into the inner surface of the lnulf a and the two wireends are connected the vone withthe other in an absolutely secure manner.

Fig. 3 shows the joining of a wire rope and wire. -Onl the part a of the muil for the rece tion-o the end of the, wire ro is 'the wire rope by strokes with a hammer so that a secure joining is produced.

According to Figs.4, 5 and 6 the end of the wire rope e and the "end of the wire b are introduced through holes d at the ends of a joining body e,r lwhereupon mulls a are vpushed over the lends ofthe wire rope and of.

the wire. The muil a for the wire vrope 1s internally threaded and the-muli for the wire has a smooth boring, the wire end being threaded. -After the mufs-a'have been put in place they yare securely fixed on the ends of the wire rope and wire by means of' v strokes of a hammer. When the joint is being put "under tension these-mulls a bear against the inner faces f of the 'ele-ment .6. In -order to prevent, in this form of conthe like is pushed over the element e.

The form of-constructionshown in Fig. 7 illustrates the joining of two wire ro acstruction, the-mulfs a from getting out of the he 4element e if the tension decreases, a sleeveg secured against displacement by a cotter or cording to the systemfillustrated inig. 4.

The ends c, lof the wire ropes are intro duced through .the holes d intor'the joining-'- element .e and internally threaded mulls are pushed over the ends of the wire ro The I' vmufs acre prevented by means o a safety sleeve c 'from getting' onto( the element e when t tension d The Ajointshown 1n Fig. 8 shows vhow 1a wire ro .fis in, a element e "ints' pulley.
